2. General information
• Infolding of the outer surface of the tooth into
its interior surface occurs
• It is a developmental variation which is
thought to arise as a result of an invagination
in the surface of Crown before calcification
3. Etiopathogenesis
• Focal growth retardation
• active proliferation
• continuous differentiation
• increased pressure
• local causes
4. Clinical features
• Commonly affected teeth is permanent maxillary
lateral incisor and maxillary Central incisor the
lower incisor or cuspid is the next common site
• there appears to be a grossly is magnified
cingulum rising to the level of the incisive edge of
the tooth
• the Crown may or may not be enlarged
• The invagination may extend to the apex of the
root
5. Diagnosis
• Infolding of tooth is seen clinically
• Inverted umbrella appearance seen
radiographically
6. Management
• To prevent caries, pulp infection and
premature loss of tooth, dense in dente must
be treated prophylactically
